We have a HP3000-9[2,3]5 and a HP9000-825 located in the same room.  I
would like to share a hp2564b printer with both systems.  The problem is
that that the 3000 send some type of setup(escape codes) to the printer,
that the 825 does not like.  Currently I have to take the printer
offline and power down the printer and connect it to the 825.  After I'm
done with I connect it back up to the 3000 and the spooler on the 3000
has to be restarted for the printer(The 3000 queriesthe printer and
finds it not in the mode it was ?).

What I want to do is put in a HP-IB switch and do the following steps:
1 Take printer offline from the 3000.
2 Switch the printer from the 3000 to the 9000.
3 Put the printer online for the 9000.
4 Change the 9000 printer model send the escape codes to reset the printer to a 
  state that the 9000 is happy with.
5 At the end of the 9000 lp model send the escape codes that set up printer for 
  the 3000.
6 Take the printer offline from the 9000.
7 Switch the printer back to the 3000.
8 Put the printer online for the 3000.

What I need to know is what does the 3000 send to the printer?

P.S.
Reality prevents me from careing too deeply that the above configuration IS NOT
supported by HP. 
8 Swith the printer back to the 3000 and hopefully the mpe/xl folks won't have    start up the spooler every time I use it.
